System and method for presenting and processing documents on the internet

ABSTRACT

A digital document delivery system and method for providing to a user an electronic primary document with associated secondary documents. The secondary documents can have relative priorities and are based upon user preference data. An electronic inserter, bill processing server and interactive bill presentation server are used to make the primary and secondary documents available for viewing by a user via the user&#39;s web browser, as well as to allow the user to interrogate the system and to respond to the primary document, such as to pay an account due as stated in the primary document. The digital document delivery system and method also notifies the user of the existence of a primary and secondary documents for viewing.

FIELD OF THE INVENTION

[0001] The present invention relates to an electronic mail delivery mechanism, particularly for the use via the Internet.

BACKGROUND OF THE INVENTION

[0002] Many businesses currently send out mass mailings to their customers or prospective customers for various business reasons. For example, a public utility such as an electrical power generating company may generate and send out hundreds of thousands of bills to its customers each month. As another example, a company may wish to send targeted marketing information, such as a sales letter to prospective customers on a mailing list. In either example, the company may wish to augment the bill or basic sales letter with additional secondary material generally referred to as “inserts”, which, in many cases, are related to specific information about the particular customer or prospective customer to which it is sent. Various companies produce mail inserting systems, such as the Pitney Bowes Production Mail Center 2000, for purposes of generating mass mailings with such inserts.

[0003] Companies that use such mail inserting systems to generate mass mailings typically use older computer systems, sometimes referred to as “legacy” computer systems due to the relative age of the computer hardware and software to generate the print data stream. These “legacy” computer systems are still found to be effective for purposes of doing mass billings and thus it is desirable to continue to use the output print stream from such computer systems for purposes of generating electronic mass mailings. Applicant's co-pending U.S. application Ser. No. 08/968,649 having Attorney Docket Number E-632 describes such a system and method for electronic and physical mass mailing in which such legacy computer systems are used and in particular, where an electronic data stream can be derived from the mainframe print stream output so as to divert some or all of the print stream information which would otherwise be sent to a physical mail delivery system to an electronic delivery system. It is there seen that an electronic inserter can use the electronic delivery print stream so as to generate a plurality of electronic documents and from there to generate electronic mail pieces which via a message router, can be delivered to the intended recipient. The electronic mail pieces each contain an electronic document and possibly one or more electronic inserts. The electronic router can output such information via e-mail, pager, fax, printer or the like.

[0004] U.S. application Ser. No. 08/968,651 having Attorney Docket Number E-685 further details a mail delivery system and method in which mass electronic mailing is accomplished by use of a database that includes a plurality of instruction templates, with each template corresponding to one of a plurality of electronic delivery mechanisms. An electronic inserter operates so as to generate electronic insert mail pieces while a computer processor is provided for associating each mail piece with at least one instruction template where each template corresponds to one of a plurality of electronic delivery mechanisms. The electronic mail piece is then delivered by the specified electronic delivery mechanism such as a worldwide web (web) browser, electronic mail (e-mail, pager, fax or printer).

[0005] For purposes of determining which of the plurality of mass mailing documents are to be sent via electronic means, U.S. application Ser. No. 08/968,498 having Attorney Docket Number E-653 describes a process for distributing messages from a sender to a recipient according to distribution preferences of the sender and the reception preferences of the recipient so that a sender can compose a message and define a set of preferences that indicate a destination, method of delivery, delivery media, class of service, carrier and other requirements pertaining to the message while the recipient can define preferences that indicate how that recipient prefers to receive messages, as well as the methods that are available for transmission. The sender thereby dispatches the message according to the sender's preferences and the recipient's preferences are analyzed to develop a set of routing rules that govern the message delivery process. Conflicts in the routing rules are resolved so that the message can be reformatted if needed, and feedback about the distribution can be provided to the sender so as to assist the sender in ascertaining the quality of service with respect to the delivery of the message to the recipient.

[0006] The present invention is directed to an improved system and method for presenting and processing primary documents, especially primary customer documents such as bills, where such primary documents may further be presented with one or more secondary documents (called “inserts”).

SUMMARY OF THE INVENTION

[0007] The present invention is directed to a digital document delivery system and method, particularly for use on the Internet and particularly for presentation of electronic bills to a customer with a mechanism for payment thereof by the customer. The digital document delivery system comprises subsystems which work together so as to provide a generalized capability to allow an end-user with an Internet browser to view an electronic version of the customer's bill which would have otherwise been printed, but which is now presented in hypertext markup language (HTML) or similar format. The recipient can then pay the bill that he or she is viewing.

[0008] The digital document delivery system comprises four subsystems which typically execute on four separate servers.

[0009] A print stream separator in combination with an electronic inserter determines which primary and secondary documents are to be presented electronically to the customer. In order to perform this task, the print stream separator separates an incoming print stream into a physical and electronic delivery print steam, with this separation based upon customer preference data. The electronic inserter then determines what secondary or “insert” documents are to be electronically referenced to the primary document as sent to a customer. These insert documents are generally referenced to the primary documents by hypertext links (sometimes called “hotlinks”). A router instruction processor (RIP) receives “send requests” messages from the electronic inserter and generates “bill request” therefrom. Each bill request is sent to a bill processing server (BPS). The RIP is responsible for collecting status information regarding the bill to be processed, as well as to make such information available to the submitting process.

[0010] The BPS acts as a fulfillment center and is responsible for monitoring the status of an interactive bill presentation server (IBPS) so as to determine when the IBPS has received the print stream data which will be transformed into a viewable electronic document. The BPS is able to respond to IBPS requests for data, including links to other worldwide web sites. The BPS is able to send e-mail messages to bill recipients so as to notify them when their electronic bill is ready for viewing. The BPS is also able to respond to bill payment requests from the end-user and to appropriately control the modification of customer debt, remittance and status data as stored in an account database.

[0011] The IBPS is responsible for interactivity with a customer's web browser. The IBPS takes the print stream data and converts it to a form viewable using a web browser. It also sends status information back to the BPS regarding the status of the bill, including if the customer has requested that the bill be paid while viewing same.

[0012] Thus the document delivery system presents an electronic document to a customer by use of incoming traditional print stream data. In addition to a print stream separator and electronic inserter, the document delivery systems includes a router instruction processor, a bill processing server receiving instructions from the router instruction processor, and an interactive bill presentation server for receipt of instructions from the bill processing server and in response to said instructions and receipt of the print stream data, generating an electronic version of the print stream data for presentation in an electronic form, as well as for receipt of response information from the customer concerning a document presented to the recipient, including presenting the response information to the bill processing server.

Detailed Description

[0017] As used throughout this description, the words “user” and “customer” are synonymous, as are the words “bill” and “primary document” and the words “insert” and “secondary document”. Definitions of acronyms are presented in Table 1.

[0018] As best seen in FIGS. 1A and 1B, a digital document delivery system 10 comprises a number of functional elements which combine to provide a system for electronically delivering documents to a recipient which would typically otherwise be generated in hard copy form. As an overview of such a system, a digital computer 12 is shown which in many applications may be a mainframe computer of the legacy type commonly used for generating customer billing. This computer generates a print data stream 14 which typically represents a stream of customer bills or the like. This print data stream is presented to a print stream separator 16. The print stream separator also receives customer preference data forming part of a customer preference file 18 via data path 19. The customer preference file forms part of the customer preference database 20 for all of the customers. Typically, this customer database contains information concerning the customers of a company which periodically generates bills to its customers. This information typically includes customer account information, mail address information, electronic mail (e-mail) address, and other demographic information concerning the customer (e.g., age, sex, hobbies, occupation) which may be relevant for purposes of generating billing or insert information. The information relevant to deciding whether a specific customer desires electronic delivery of documents, and, if so, the demographic information relevant to secondary document selection (e.g., age, sex, hobbies, occupation, etc.), is transferred to the print separator via data path 19.

[0019] The print stream separator receives this information along with the print data stream 14 and determines which print data should be sent to a high speed printer 22 via hard copy output data stream 24 and which information should be presented to an electronic inserter 26. The print data sent to the electronic inserter includes an electronic print stream 25 representing the primary document to be electronically delivered. The print data also includes electronic mail run data in a specific format known as Electronic Mail Run Data File Specification (EMRDF) by means of an electronic output data stream 28. This data contains information concerning secondary documents to be associated with the primary document, with the secondary document data based upon the specific customer preference file.

[0020] The electronic inserter also receives customer account information and general customer information via data path 30 which forms part of the customer preference file 18. The account information contains general customer information, such as postal mailing addresses, e-mail addresses, bank account information and the like. It is also directly transferred from the customer preference database to the electronic inserter via data path 30. Of course, other information could be included, such as customer facsimile number, beeper number and the like for purposes of primary document notification.

[0021] The electronic inserter performs a function similar to that performed by inserting systems that generate inserts to accompany customer bills when bills are generated in hard copy.

[0022] The electronic inserter also receives information from a job set-up application module 32 which contains information concerning the types of inserts which are available for insertion by the electronic inserter and the electronic slot location for these inserts. This information concerning the specific job is known as job set-up data and contains information concerning hypertext links to electronic locations where such insert information is available. Thus, the electronic inserter need not actually generate the specific insert information to accompany the customer bill, but, rather, need only include the electronic link to such information for ultimate presentation to the customer in an electronic form. For example, accompanying a customer utility bill might be one or more links which when clicked upon in a browser, such as the Netscape Navigator™ browser or Internet Explorer™ browser, would cause the user to connect to that link for presentation of specific insert information, which may be an advertisement, informational data or the like. The electronic inserter 26 thus performs a function analogous to a hard copy inserting system but without the need for electronically generating an analogous electronic copy of each insert but rather electronically generating information regarding a link for obtaining such information when the customer desires to view it.

[0023] The output of the electronic inserter is typically a file in AFP format. This output is presented on data path 34 of the electronic inserter. In this way, the file structure for the bill is in the same format as that which would be presented if print output were to be generated. Of course, other file formats could be used.

[0024] The electronic inserter communicates with a router instruction processor (RIP) 36. The RIP communicates with the electronic inserter via communication path 38 so as to send status information to the electronic inserter as well as to receive bill requests (BR) from the electronic inserter. The bill request instructs the RIP to generate a bill request via communication path 40 to a bill processing server (BPS) 42. The bill processing server also communicates via communication path 40 with the RIP to send bill status information to the RIP. Information regarding secondary documents to be associated with the primary document is also transferred to the RIP by the electronic inserter.

[0025] In operation, the RIP sends the bill request to the BPS so as to initiate the generation of a notification to the appropriate customer.

[0026] The BPS monitors the interactive bill presentation server (IBPS) 44 via communication path 46. The IBPS is responsible for receiving the electronic print data stream files via communication path 34 and processing these documents so as to be later presentable to the customer. It is only after the documents have been so pre-processed that the customer can actually view the primary document (bill) and the associated secondary documents (inserts) via a web browser over communication path 48 forming part of the Internet. The IBPS is also responsible for generating account information known generally as bill status update information which is communicated to the BPS. This bill status update information typically includes the customer account number, the date the bill was run, whether the bill has been loaded, whether it has been accessed by the customer, whether it has been paid by the customer and the like. Some of this information as generated by the IBPS is received via communication path 48 from the customer at his or her computer via the associated browser software 54 that is run on the customer's computer 52.

[0027] In the preferred embodiment of the present invention, the IBPS generates the Internet browser viewable data stream when requested by the customer by use of the @ Work Technologies Internet billing system known as the WorkOut™ Internet Billing System for generating browser viewable information such as in hypertext markup language (HTML) or other browser compatible languages (now or in the future) such as Extensible Markup Language (XML) and Java. As seen in FIGS. 1A, 1B and 3, it should be noted that in operation the IBPS receives the raw print data from the electronic inserter and generates an intermediate document corresponding to this print data using the XML language, which in turn is stored and indexed in intermediate document database 61, such as an Oracle™ database. Part of the information for generating this intermediate document is derived from design and build document templates 63. The location for placement of secondary document links based upon the received priority of the secondary document from the EMRDF file, and the overall design of the primary document, can be stored in these templates.

[0028] The IBPS receives the specific links (called “hotlinks”) for the secondary document from the BPS. The BPS also acts as an electronic “traffic cop”, by not allowing the IBPS to generate viewable documents unless the BPS has determined that all related documents and account information is ready for viewing.

[0029] The BPS 42 communicates with a bill remittance and status data database 56 via communication path 58 for retrieving and updating bill remittance and status data concerning customer bills based upon information received by the bill processing server from the IBPS which in turn receives information from the customer via the Internet and the associated browser communicating with the Internet.

[0030] The BPS furthermore is responsible for notifying the customer that a bill or other information is available for viewing via the Internet. The BPS performs this task in any of a plurality of manners, such as by generating an e-mail notification message which can be sent over the Internet to the customer's e-mail address as diagrammatically shown by e-mail event 60. Of course, other methods could be used by the BPS to notify the customer, such as generating a facsimile message and sending it via facsimile to the customer's facsimile machine, by generating a beeper message for presentation to the customer's beeper; or even by generating a print mail message to be delivered to the customer's mail address.

[0031] The BPS is also responsible for generating daily reports concerning the overall status of the digital document delivery system. These reports can be communicated to a biller module 62 via communication path 64 and may contain such information as daily account receivable reports, information concerning customers that have not paid their respective bills for a certain period of time, customers who have not viewed a bill after a certain period of time, etc.

[0032] The BPS is responsible for generating information for presentation to an associated bank 66 via communication path 68. Such information would typically include daily ACH Batch Feed File information and any other information which the proprietor of the digital document delivery system wants to communicate with its associated bank.

Summary of Operation of Digital Document Delivery System

[0036] In view of the description above, the overall operation of the digital document delivery system is to generate a print stream of data, typically in a format compatible with that used in current hard copy printer print stream data, such as in the AFP file. This information is generated via an electronic inserter which receives data concerning a customer's bill as well as inserts to be presented in that customer's bill based upon the associated customer's preference file. This information is communicated to an interactive bill presentation server which takes the information and generates an output (based upon pre-processed information and downloaded servlets concerning the design of the bill) which is compatible for viewing such information over the Internet by means of browser software executed on the customer's personal computer so as to generate screens of information which look essentially similar to a hard copy bill and associated inserts that the customer would receive had the bill been generated by traditional print means. This is shown diagrammatically in FIGS. 1A and 1B as bill 70 with its associated inserts.

[0037] The interactive bill presentation server is under the control of the bill processing server which, in turn, is responsible for updating associated account database that contains information concerning the status of bills, payments thereof, etc., by the associated customer, as well as for notifying the customer of an existence of a bill for viewing via a web browser. The bill processing server, in turn, communicates with a router instruction processor which interacts with the electronic inserter, as well as informing the bill processing server of the generation of an electronic print stream associated with a bill and associated inserts for presentation to the interactive bill presentation server. The interactive bill presentation server receives instructions from the customer via the Internet which, in turn, are communicated to the bill processing server for updating bill remittance data and the like, upon the customer indicating his or her desire to pay an associated bill received electronically. Bills are only made available to a customer when all necessary information for viewing has been pre-processed. An enrollment application module is also made available to prospective/current customers to allow them to create/update information in their customer preference file.

[0038] The overall result of the present digital document delivery system and method is an electronic analog of the traditional hard copy printed bills generated by traditional high speed printer and mail inserting systems and associated computers that instruct such systems with regard to generating bills and associated inserts. The present invention eliminates the paper associated with traditional print systems, provides an electronic analog to the bill received so that the bill format is familiar to the customer, provides easy means for the customer to pay such bills, as well as to view associated inserts having links sent with the bill.

[0039] Furthermore, the overall digital document delivery system and method allows the proprietor of such an overall system to monitor the activities of its customers with respect to when they view their bills, what inserts they retrieve, when they pay their bill(s), etc., thereby giving the proprietor of the digital document delivery system better information concerning its customer base, their likes and dislikes, based upon their viewing or not viewing associated insert information, and the like. This, in turn, allows the proprietor of the digital document delivery system to modify the customer preference file for associated customers so as to present to such customers inserts which would be more desirable for viewing by that customer, and thereby enhancing the overall delivery of bills and inserts to its customers.

[0040] Although a web browser is used in the present invention for Internet presentation of information to the customer and for receipt of information from the customer, any electronic communication means, including an Intranet or any other form of electronic delivery which is viewable by a customer with the customer's associated viewing equipment (which would typically be a browser program run on a personal computer), could be utilized for presentation and receipt of electronic information to the associated customers of the proprietor of the digital document delivery system.

[0041] Furthermore, although the customer bill information is shown as being separated by a print stream separator 16 with the original customer bill information generated by a digital computer where at least some of the information may be presented to a traditional high volume printer, all of the information could, in fact, be generated in electronic form without the need for such a print stream separator. Furthermore, the format of such bill information need not be in any specific form prior to generation of the electronic version for viewing by the customer's browser as generated by the interactive bill presentation server.

[0042] Although the electronic inserter, router instruction processor, bill processing server and interactive bill presentation server are shown as separate modules, some or all of these modules may, in fact, reside on the same digital computer server.

[0043] In summary, the digital document delivery system provides a primary document (such as a bill) and associated secondary documents (such as inserts) for each identified user (customer) having an associated customer preference file. The selection of secondary documents can be based upon information in a customer's preference file. The customer can communicate with the digital document delivery system, obtain information therefrom, and perform tasks therewith (e.g., pay a bill).
